I have a 2020 Frame and I can get rid of Soap Opera mode by going to "Settings > Picture > Expert Settings > Picture Clarity Settings "and changing the "Auto" setting to "Off".
You can also reduce the effect to by changing the setting to "Custom" and adjusting the Judder Reduction and Blur Reduction to lower numbers.
You may have something similar on your 2020 model.
I have turned this off and also tried to set custom mode with 0 for all settings but I am still getting the soap opera effect.
I have the 55" Q70T
I thought I was making an upgrade but I'm starting to hate watching TV and movies now. I am really thinking about going back to my 47", non 4K 2014 model.
Same here. We have the q80t and we can't turn it off completely either. It's really unfortunate. Hopefully Samsung updates the firmware with this as an option to turn off in the future.
I had this same problem with the Q90T. Soap opera effect no matter what. It made movies unbearable. I ended up returning it and getting a Sony 950H. It's unfortunate because black levels and HDR highlights were amazing, plus I bought an HW-W950T so Q-symphony would have been awesome but Samsung gave me BS answers when I reached out to support so Sony Tv and Samsung bar it is.
